JpHN MESNY TO URTEL, OF LONDON, ENGLAND;

ADDING AND PRINTING MACHINE.

To all whom it may concern Be itknown that I, J OIIN Mass Y TOURTEL, acitizen of the United Kingdom of Great Britain and Ireland, and residentof 57 Chiswell street, London, England, have invented certain new anduseful Improvements in Adding and Printing Machines, of which thefollowing is a specification, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in adding machines of the kind inwhich the amounts are set by rotating toothed sectors through thenecessary angle whereon the printing of the amount and the operation ofadding are etfected by means of separate handles or leversf The mainobject of the present invention, is to insure the correct operation ofthemachine in a definite sequence, so that the amount set will beproperly printed and added withas great accuracy and surety as this isdone in the more expensive and elaborate machines employing key leversand a. single handle.

The invention further relates to novel constructional f *atures whichwill be more readily understood from the following description, whilethe novel features are pointed out in the appended claims. 7

In the drawings which illustrate one form of the invention by way ofexample, Figure 1 is a separate detached side elevation of the lockingslide which performs an important function in this invention. Fig. 2 isan end view of the slide shown in Fig. 1. Fig. 3'is a. side view of themachine looking on'the opposite side to that. on which the operatinghandle is arranged; the printing lever and the pivoted plate cooperatingtherewith are omitted. Fig. 4 is a view similar to Fig. 3,

. with the printing lever and its cooperating pivoted plate shown inposition during operation. Fig. 5 is a view similar to Fig. 3, showingthe parts which cooperate with. the printing lever, in their idleposition. Fig. G-is av partial sectional side elevation similar to Fig.4, with the parts in the idle position represented in Fig. 5. Fig. Tis aside elevation witli certain parts removed, looking onthe opposite sideto Figs. 36, the parts being in the idle position represented in Figs.5:"and (5. Fig. 8 is an outside view similar to Fig.7, with the partsall'in place. Fig.

Fig.15 is a detail view of the restoring lever which returns those sectorsto theirinitial positions which have over-run during the process of tenscarrying. Figs. 16 and 17 are front and rear views respectively of theentire machine, while Fig. 18 is a plan view.

The sectors 3, are separately mounted 'on a sleeve which surrounds theoperating shaft 1. Each sector is provided with teeth 3, over one partof its circumference and type 42 (Fig. (3) over another part. Thesectors together with the shaft are supported in a housing formed of twoside checks ,2, and a curved sheet metal casing 2*, these parts beingconveniently fixed on a hollow "cast metal base. of finger pieces 4,(Fig. 1(3) which project through slots in the case.

Printing.Having set. the sectors 3, the next operation is to print theamount registered. A roll of paper 46, is carried by two side cheeks 45,fixed to oscillate with a shaft 44, operable by the printing lever 43.The shaft 44, is also controlled by a coiled spring 49, attached to anarm 44, both the arm and the coil spring being located within the hollowcast base. The paper passes from the i v roll 46, around the pressureroll 47, and then off by the take off or tauteningroll 48.

Mounted above the roll 46, there is the inking pad it, carried by thearmh mounted on a spindle m, supported in-lugson/the sidecheeks 2, of themachine. Around the spindle m, there is a spring 71, (see Fig. 17

The sectors are set by means which always tends to pressthe inking-pad J44, engages a plate 44 which bridges the Eli) .. type on the sectors totjwo side cheeks 45, and thereby the paper and the .roll 47, are broughtagainst the receive the impression of the amount set. It will beunderstood that the operation just described has oscillated the plateis, from the posit-ion shown iii Fig. 6, to that shown in Fig. 4. To theplate 70, there is fixed a pin is, which projects through and moves in acurved slot la, in one side cheek 2 of the machine, that is to say theleft hand check in Figs. 10, 16 and 18. On the inside face of this cheekthe slide 0., shown in detail in Fig. 1, is mount ed. The slide a ismounted close up to the internal surface of the side cheek 2, and isguided on two pins A. Fig. 3) fixed in the side cheek 2, and projectingthrough slots A, on the slide a. The slide a is provided with an openinga, which, when the slide is in position comes opposite the slot M, inthe side cheek (see Fig. 8). The pin mentioned above thus pressesagainst the side of the opening a, and draws the slide a, from right toleft in Fig. 3. The slide a, is pro-.

vided with a bar I), extending at right angles to the slide and acrossthe sectors 3. WVhen the slide is moved as described, the bar 6 entersthe teeth of the sectors and locks them against further movement. Thislocking operation isinitiated before the actual impression and iscompleted simultaneously with the completion of the printing. The barI), thus, not only locks the sectors but assures the alinement of theprinting. This completes the-actual printing operation, after which, aswill be understood, the bar 6, leaves the type sectors locked.

Adding.-During the printing operation, the adding lever 10, has beenlocked, but at the completion, the adding lever-or handle 10, isreleased. The handle 1,0, is fixed to the shaft l, and on the same shaftthere is fixed a composite cam 7 as well as the usual operating cam 11.The ram .1", is provided with a rim rf having a projection r. Normally,when the machine is idle, the projection 1" restsagainst the arm Q2 of alever q,

pivoted at 9 The lever g, is also provided with an arm 9', which restson the raised part 7), of a segment 27, mounted on the printing shaft44. The segment 79, is arranged at the opposite side of the machine tothe printing lever 43, (see Figs. 8, 9 and 11). When the-printing lever43, is operated, the segment p, moves from the position shown in fulllines in Fig. 9, to the poi,o21,5ss

sition shown in dotted lines, whereby the arm falls by gravity in theform shown on to the part of the segment 79, of smaller radius. Thiscauses the arm 9, to move away from contact with the projection r. Thearm 9 of the lever is provided for co-acting with a spring which is notillustrated in the drawings. the shaft 1, and handle 10, can only berotated in one direction on account of the detent ratchet and pawl s ands, the ratchet wheel .9, being fixed on the shaft 1, while the'pawl s,is carried by the housing 2. As

As will be seen from Fig. 9,.

soon as the arm g drops from the projection 1", the shaft 1, may berotated counterclock-wis'e in Fig. 9. When the shaft 1 1s rotated, theoperating cam 11 is carried around with it and this cam cooperates witha mechanism known in itself,'and which forms no part of the presentinvention, to rotate the pinion 7, which is fixed to rotate with the arm6. The arm 6, as is known carries a pin 8, projecting through slots inall the sectors and returns these sectors to their normal position. Thismechanism is well known, and is not illustrated in the drawings. Therotation of the cam r, oscillates a lever 15 (see Fig. 8) which bringsthe adding mechanism into engagement with the teeth 3, of the sectors.The arm 15, is mounted on a shaft 13 which passes through the casing andhas fixed to it side cheeks which carry the zeroizing counting and tenscarrying mechanism, the first counting wheel being illustrated in Fig.6.

The method has been described by means of which the operating handle islocked and released and the initial operation of the operating handle asdescribed brings the counting mechanism into engagement with the sectors3, by means of the cam r, and then returns the sectors by means of thecam ll, both-of which cams are mounted to rotate with the shaft 1. Asthe cam r, rotates,

the projection 1" moves around till it engages the arm When theprojection 7", co-acts with the arm 1*, the lever g is brought back tothe position illustrated in full lines in Fig. 9. The printing lever 43,as will be understood, has been held in the position shown in Fig. 4, bythe arm 9, engaging on the shoulder 29, of the segment As soon howeveras the projection 1 raises the arm and thereby the arm (1, the segment7/,and lever 43, spring back under the action of the spring 49. j Asmentioned at the close of the description relating to the printingmechanism, the

sectors 3, are locked by the bar 5. The initial movement of the handle10, is utilized not only to operate the arm 15, but also to move backthe slide a. The. operation is such that the slide a, is moved backsimultaneously with the operation of the arm 15.

For the purpose of moving back the slide a,

the shaft 1 is provided With a cam 2, shown in dotted lines in Fig. 3,and shown in full in the plan view, Fig. 11. 'lhe'cam z, is' providedwith a nose 2, which as shown in and thereby draws the bar I), with itsnose 6', out of engagement with the teeth of the sector 3.Simultaneously with the'bar 6,

moving out of engagement with the sectors- 3, the counting mechamsm 1smoved into en-' gagement with these sectors by means of the arm 15. Thecam 2 extends over a suitable are so as to insure that the slide a, willnot slip back by any vibrations which may be imparted to the machine.

According to this invention the operation of carrying the tens iseffected while the counting mechanism is in engagementwith the toothedsectors. This method of operation is not" broadly new. this methodof'operat-ion that the cam 1", shown in Fig. 12, is of circular form forsuch a large part of-its circumference. It will be understood thereforethat the finger pieces 4, are all returned to their zero position by theoperation of the cam 11. If new any tens have to be carried, it is clearthat the fingers 4, must be capable of moving one step behind their zeroposition. To enable this, the slots in the casing for the finger .pieces4, are continued rearwardly for a short distance and in their zeropositions the finger pieces 4, rest against a transverse rest bar to.The transverse rest bar w, is carried by a lever pivoted at w, andhaving a depending arm w (see Figs.- 2 and 7). The depending arm 10 isarranged in the path of the projection 1- on the cam r. \Vhen theprojection 7' leaves the circular part 20 on the interior edge of thedepending arm w", the arm w, swings clockwise in Fig. 7, under theaction of the weight of the bar to. The finger pieces are all brought totheir zero position while the projection r is still in engagement withthe circular part. in, and the operation of tens carrying commences assoon as the projection 7"" leaves the circular part 11;. The necessaryfreedom of motion forthe finger pieces 4, is thus provided for. \Vhenthe rotation of the shaft 1 is completed the projection r, again comesto bear on the bottom of the circular part 10 of the lever 10", andtherebyrestores the finger pieces 4, to their zero position.

Totalizz'ng and zc2'0i.ei7z .As mentioned above, the counting mechanismis normally out of engagement. with the sectors. 111 this positionzeroizing is effected merely by rotating the zeroizing handle 37. Thezeroizing handle 37, has a hub plate (I, provided with a flange brokenat d, so as to allow the hu plate to. pass over a pin 6, fixed in the Itis because ofside cheek of the casing. The zeroizing shaft 23, and thehandle 37, are mounted to move with the counting mechanism in the knownmanner. Thus at every operation of adding, the. opening d, permits themo-' tion of'the hub plate (I, over the pin 6. As shown the pin 6 is cutaway on one side to permit of the rotation of the handle 37 when theapparatus is at rest.

For the purpose of totalizing the counting mechanism is moved 'intoengagement with the sectors 3, by means of a lever c. The lever c, isprovided with a projecting arm carrying a nose piece 0, adapted toengage a pin a, on one of the side checks of the' counting mechanism(see Fig. 6). The nose 0 is also adapted to engage the edgea of theslide a, (seeFig. 3). thus moved from right to left in Figs. 3 and 5, soas to bring the nose I), of the bar b, into engagement with the teeth ofthe sectors 3. At the same time, the hub 03, and the zeroizing andtotalizing arm 37 is moved over the pin a, into the position shown inFig. (3. In this position it is rotated. As will be readily understoodthe rotation of. the arm 37, brings the counting mechanism into positionwith the figures all registering zero. The zeroizing mechanism is notnovel and for the sake of simplicity is omitted from the drawing. Inconsequence of this, the sectors 3. are moved through amountscorresponding to the total. To enable the sectors3, to move the bar Z),the slide plate a, must be withdrawn from engagement with the teeth Thisis effected by means of a cam f, mounted on the zeroizing shaft 23. Thecam f is provided with a piece f, which on rotation of the shaft 23,engages the nose piece of, on the plate a, and thereby moves the plate afrom left to right in Fig. 5. The sectors3 are then rotated to bringthem into the position to register totals, whereupon the total isprinted by the; operating,printing lever 13 Toward the end of therotation of the shaft 23, a pin 9 on the cam f, engages the end (L ,.0fthe plate (I, and thereby moves the slide a, into looking position afterthe sectors have been set to register the total. During the printing operation in this'case therefore, the slide a. will not require to beoperated by the pin 76 Forthe purpose of holding the arm 37 in its'normal zero position (l opposite the pin 6, a

spring 37 with a projecting rib 37 is fixed to the side cheek of themachine.

Summing up, it will be seen that the slide a, controls the sequence ofoperations asfollows:-At printing, the lever 4.3 is operated to printand bring the locking slide a, into engagement with the sectors. Thisoperation also releases the means (the lever g) for locking theoperating handle. The rotation of the operating handle 10 now releasesthe locking slide a, and simultane- The slide-a, is

ously' brings the counter mechanism through the lever 15, intoengagement with the toothed sectors.
